RESUMEN
Ectopic eruption of the tooth is a developmental disturbance where the tooth does not erupt in a normal position. This may be due to arch length deficiency or due to, delayed or premature exfoliation of deciduous teeth, or a combination of the above. A total or complete absence of teeth is called true anodontia; if one or more teeth are missing, it is called partial anodontia. It can be syndromic or non-syndromic in occurrence. Here, we present a rare case of non-syndromic partial anodontia and ectopic eruption of permanent mandibular canine in a female patient.
RESUMEN
The Carabelli cusp (Cusp of Carabelli) is a tubercle or the extra fifth cusp found on the mesiopalatal cusp of the maxillary permanent and deciduous molars. It is nonfunctional but it can be used to distinguish populations and is also used in forensic and anthropological studies. This condition is uncommon on deciduous teeth. In this case report, we present a rare case of unilateral presence of cusp of Carabelli in deciduous dentition.
RESUMEN
Oral habits are an acquired mode of behavior that has become nearly or completely involuntary. Oral habits such as thumb sucking, lip sucking, tongue thrusting, lip biting, nail biting, object biting, and bruxism have serious health consequences. Several etiological factors have been linked to the development of oral habits. In this article, a rare case of a scar on the lower lip, which occurred due to lip biting habit, has been reported.
